With a deficit of sediment needed to compensate for relative sea level rise, a new study demonstrates that organic material cannot be ignored in evaluating mass and volume accumulation rates.

Soil Remains Warmer and Drier After Long-term Warming Stops
Pausing a long-term soil warming experiment revealed that previously warmed plots remained both warmer and drier compared to plots which had not experienced previous soil warming.
Geology and Chemistry Drive Animal Migration in the Serengeti
Fieldwork in Tanzania suggests that soil chemistry—influenced by local volcanism and tectonic activity—might help dictate the record-setting migration of over a million wildebeests.
Floating Patches of Soil Nutrients in Soil Help Explain Arctic Thawing
Nutrient-rich diapirs have a complex relationship with soil microbes and play an important role in carbon and nitrogen nutrient cycling, making them crucial for understanding feedbacks in the Arctic.
Florida Coastlines Respond to Sea Level Rise
For more than a century, carbon burial rates have been increasing on some southern Florida coasts. Scientists now verify this trend and propose an explanation.
Podcast: Exhuming a Buried Piece of American History
Scientists are using grave soil to reconstruct the lives of enslaved Africans in colonial New York.
Southern California Climate Change over 100,000 Years
Researchers used a sediment core from a lake in California’s San Bernardino Mountains to track the effect of climate on vegetation, fire, and erosion between about 120,000 and 15,000 years ago.
Repeating Famous Hillslope Experiment Provides New Insights
Repeating a famous hillslope experiment after 55 years shows that soil properties can change within several decades and highlights the importance of a leaky boundary for hillslope drainage.
Minireservoirs Could Save Farmers with Sandy Soils
A recently revived subsurface water retention technology could conserve water and drastically increase crop yields in arid landscapes with sandy soils like sub-Saharan Africa.
Rating Fire Danger from the Ground Up
Soil moisture information could improve assessments of wildfire probabilities and fuel conditions, resulting in better fire danger ratings.
